Get this mapping under way to get a very clear picture of the ocean floor if it all goes properly, carol. if it all goes properly. just to reiterate it takes, what, two hours just to get down two and a half miles under water, right? yeah. then it will be down there for like 16 hours or something like that? right. two hours to go back up to the surface and then what happens? then like four hours to unload all the information from it. one of the things i really want to stress here because it s very important, this depends entirely on this, the surface of the water. i was talking to somebody who is very experienced with these and he was telling me, he said, look, if you do not have the right circumstances up here on top of the water, this is an inherently hazardous job. offloading it is difficult to make sure you don t damage the instrument, the ship, hurt anyone on board. these are notoriously rough seas ....

Weather conditions and because of the time, the weather detection is greatly diminished. air and surface search will be concluded in the next two days or so and they are going to have to consult with everyone else involved to see how it goes forward. that s a huge development. i think he characterized it very well. one thing that he struck me that said is this area is unknown to man and by that he means, there is no data. we don t even know what the depth ares in detail. we know generally. there could be ridge systems, mountain ranges that have been never detected. to send an autonomous vehicle down near the bottom and start mapping in that area can be actually quite risky. i think they are going to be very cautious in their initial deployments and they may be ....

This is a very forbidding environment. it s cold. just above freezing. it s completely dark. and we really don t know much about the ocean floor here. you might say why not just drop that robotic sonar imaging device there and let it ride around and start mapping all of this? if you want the best performance out of something like this, you d like to get it as close to the right distance from the floor as possible. this is right at the range of its functioning level here, 2.5 miles down. they have to make sure they have a better idea before they turn it loose. what that means is up oen the surface they re going to spend a little more time with things like the hms echo trying to get a better map of the ocean floor in general. if they have that they ll know where the obstacles are. they ll know how to place that robot and get better results. tom foreman there with some fascinating insight. and each day we learn more about the challenges the searchers face as they try and locate this ....

You re not here. out of sight, i don t want to say it always there for you. how s the nose doing? good? it s a little crooked. have to get it set tomorrow. miles took a tumble. we re worried. went down hard. thank you for asking. appreciate it. do you agree, the time is probably up for pingers and i do. and start phase two, putting submersibles in the water, correct? i do. if you talk to oceanographers, put the submersible in now, get uav in and start mapping. they ll probably give it a few more days in case they hear the faint last bit of ping. it occurs how lucky they were to capture the pings. so that was an extraordinary piece of luck. i still, still wonder what secret asset, whether it was the australian over the horizon radar, whatever it was that put them on that location effectively. that was an amazing piece of ....

We won t know what it s like until they get what those auvs in the water, right? to see it? sure. you know, don, these are depths and places, kinds of underwater ter rains th s thas that oceano are very familiar with. it s half the ocean depth. as we speak on the other side of us aly thattia, north of new zealand, a team is mobilizing to go between six and seven miles wery a robot and do exploring there. the depths aren t so intimidating. the terrain, i can see it because my thesis was spent poking around terrains like this. rocks on a sediment volcanic terrain. that s not intimidating either. trying to find the black boxes, a particular bit of a needle in that big haystack will be problematic and takes systematic mapping of that terrain. michael what did you want to add? i wanted to say that s actually one of the key ....
